INTRODUCTION
The metal lathe is used to remove material from
a rotating workpiece, which is held in place on
the spindle with a chuck or faceplate. The cutting
tool is mounted on the carriage or tailstock and
moved against the spinning workpiece to perform
the cut.
Typical metal lathe cutting operations include fac-
ing, turning, parting, drilling, reaming, grooving,
knurling, and threading. There are a wide variety
of tools and workpiece holding devices available
for each of these operations.
Models G0602 and G0752 both require setting
gearbox dial positions and positioning V-belts to
select the spindle speed. However, the Model
G0752 features an electronic variable-speed con-
trol and digital RPM display that make it possible
to select speeds within the selected range while
the machine is running.

Model G0602/G0752 (Mfd. Since 03/17)
-11-
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece mate-
rial. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hear-
ing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifica-
tions—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement dur-
ing operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for rec-
ommended accessories. Using improper acces-
sories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!
MAINTAIN POWER CORDS. When disconnect-
ing cord-connected machines from power, grab
and pull the plugNOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intend-
ed operation, stop using the machine! Contact our
Technical Support at (570) 546-9663.

Model G0602/G0752 (Mfd. Since 03/17)
Additional Safety for Metal Lathes
CLOTHING, JEWELRY & LONG HAIR. Tie back
long hair, remove jewelry, and do not wear loose
clothing or gloves. These can easily get caught on
rotating parts and pull you into lathe.
ROTATING PARTS. Always keep hands and body
at a safe distance from rotating parts—especially
those with projecting surfaces. Never hold any-
thing against rotating workpiece, such as emery
cloth, that can pull you into lathe.
GUARDING. Guards and covers protect against
entanglement or flying objects. Always ensure they
are properly installed while machine is running.
ADJUSTMENT TOOLS. Remove all chuck keys,
wrenches, and adjustment tools before turning
lathe ON. A tool left on the lathe can become a
deadly projectile when spindle is started.
SAFE CLEARANCES. Before starting spindle,
verify workpiece has adequate clearance by hand-
rotating it through its entire range of motion.
NEW SETUPS. Test each new setup by starting
spindle rotation at the lowest speed and standing
to the side of the lathe until workpiece reaches full
speed and you can verify safe rotation.
SPINDLE SPEEDS. Using spindle speeds that are
too fast for the workpiece or clamping equipment
can cause rotating parts to come loose and strike
nearby people with deadly force. Always use slow
spindle speeds with large or non-concentric work-
pieces. Never exceed rated RPM of the chuck.
LONG STOCK SAFETY. Long stock can whip
violently if not properly supported. Always support
any stock that extends from the chuck/headstock
more than three times its own diameter.
CLEARING CHIPS. Metal chips can be razor
sharp. Avoid clearing them by hand or with a rag.
Use a brush or vacuum instead.
SECURE WORKPIECE. An improperly secured
workpiece can fly off spindle with deadly force.
Make sure workpiece is properly secured before
starting the lathe.
CHUCKS. Chucks can be heavy and difficult to
hold. During installation and removal, protect your
hands and precision bed ways by using a chuck
cradle or piece of plywood over the bed ways. Use
lifting equipment, as necessary, for large chucks.
STOPPING SPINDLE. Always allow spindle to
completely stop on its own, or use a brake, if
provided. Never put hands or another object on a
spinning workpiece to make it stop faster.
CRASHING. A serious explosion of metal parts
can occur if cutting tool or other lathe component
hits rotating chuck or a projecting part of work-
piece. Resulting metal fragments can strike nearby
people and lathe will be seriously damaged. To
reduce risk of crashing, ALWAYS release automat-
ic feeds after use, NEVER leave lathe unattended,
and CHECK all clearances before starting lathe.
COOLANT SAFETY. Coolant can become very
toxic through prolonged use and aging. To mini-
mize toxicity, change coolant regularly. When
using, position nozzle properly to avoid splashing
operator or causing a slipping hazard on floor.
TOOL SELECTION. Cutting with incorrect or dull
tooling increases risk of injury from broken or dis-
lodged components, or as a result of extra force
required for operation. Always use sharp tooling
that is right for the job.
SANDING/POLISHING. To reduce risk of entan-
glement, never wrap emery cloth around rotating
workpiece. Instead, use emery cloth with the aid
of a tool or backing board.
MEASURING WORKPIECE. To reduce risk of
entanglement, never measure rotating workpieces.
Serious injury or death can occur from getting entangled in, crushed between, or struck by
rotating parts on a lathe! Unsecured tools or workpieces that fly loose from rotating objects

Availability
Before installing the machine, consider the avail-
ability and proximity of the required power supply
circuit. If an existing circuit does not meet the
requirements for this machine, a new circuit must
be installed. To minimize the risk of electrocution,
fire, or equipment damage, installation work and
electrical wiring must be done by an electrician or
qualified service personnel in accordance with all
applicable codes and standards.
Electrocution, fire, shock,
or equipment damage
may occur if machine is
not properly grounded
and connected to power
supply.
Full-Load Current Rating
The full-load current rating is the amperage a
machine draws at 100% of the rated output power.
On machines with multiple motors, this is the
amperage drawn by the largest motor or sum of all
motors and electrical devices that might operate
at one time during normal operations.
The full-load current is not the maximum amount
of amps that the machine will draw. If the machine
is overloaded, it will draw additional amps beyond
the full-load rating.
If the machine is overloaded for a sufficient length
of time, damage, overheating, or fire may result—
especially if connected to an undersized circuit.
To reduce the risk of these hazards, avoid over-
loading the machine during operation and make
sure it is connected to a power supply circuit that
meets the specified circuit requirements.
For your own safety and protection of
property, consult an electrician if you are
unsure about wiring practices or electrical
codes in your area.
Note: Circuit requirements in this manual apply to
a dedicated circuit—where only one machine will
be running on the circuit at a time. If machine will
be connected to a shared circuit where multiple
machines may be running at the same time, con-
sult an electrician or qualified service personnel to
ensure circuit is properly sized for safe operation.
A power supply circuit includes all electrical
equipment between the breaker box or fuse panel
in the building and the machine. The power sup-
ply circuit used for this machine must be sized to
safely handle the full-load current drawn from the
machine for an extended period of time. (If this
machine is connected to a circuit protected by
fuses, use a time delay fuse marked D.)
110V Circuit Requirements
This machine is prewired to operate on a power
supply circuit that has a verified ground and meets
the following requirements:
Serious injury could occur if you connect
machine to power before completing setup
process. DO NOT connect to power until
instructed later in this manual.
Model G0602/G0752 (Mfd. Since 03/17)

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is nec-
essary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service per-
sonnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, discon-
nect it from power, and immediately replace it with
a new one.
Extension Cords
We do not recommend using an extension cord
with this machine.
If you must use an extension
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Minimum Gauge Size ...........................14 AWG
Maximum Length (Shorter is Better).......50 ft.
Grounding & Plug Requirements

SHOCK HAZARD!
Two-prong outlets do not meet the grounding
requirements for this machine. Do not modify
or use an adapter on the plug providedif
it will not fit the outlet, have a qualified
electrician install the proper outlet with a
verified ground.
This machine MUST be grounded. In the event
of certain malfunctions or breakdowns, grounding
reduces the risk of electric shock by providing a
path of least resistance for electric current.
This machine is equipped with a power cord that
has an equipment-grounding wire and a grounding
plug. Only insert plug into a matching receptacle
(outlet) that is properly installed and grounded in
accordance with all local codes and ordinances.
DO NOT modify the provided plug!

Model G0602/G0752 (Mfd. Since 03/17)
The unpainted surfaces of your machine are
coated with a heavy-duty rust preventative that
prevents corrosion during shipment and storage.
This rust preventative works extremely well, but it
will take a little time to clean.
Be patient and do a thorough job cleaning your
machine. The time you spend doing this now will
give you a better appreciation for the proper care
of your machine's unpainted surfaces.
There are many ways to remove this rust preven-
tative, but the following steps work well in a wide
variety of situations. Always follow the manufac-
turer’s instructions with any cleaning product you
use and make sure you work in a well-ventilated
area to minimize exposure to toxic fumes.
Before cleaning, gather the following:
Disposable rags
Cleaner/degreaser (WD•40 works well)
Safety glasses & disposable gloves
Plastic paint scraper (optional)
Basic steps for removing rust preventative:
1.
Put on safety glasses.
2.
Coat the rust preventative with a liberal
amount of cleaner/degreaser, then let it soak
for 5–10 minutes.
3.
Wipe off the surfaces. If your cleaner/degreas-
er is effective, the rust preventative will wipe
off easily. If you have a plastic paint scraper,
scrape off as much as you can first, then wipe
off the rest with the rag.
4.
Repeat Steps 2–3 as necessary until clean,
then coat all unpainted surfaces with a quality
metal protectant to prevent rust.
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. Avoid
using these products
to clean machinery.
Many cleaning solvents
are toxic if inhaled. Only
work in a well-ventilated
area.
NOTICE
Avoid chlorine-based solvents, such as
acetone or brake parts cleaner, that may
damage painted surfaces.
